WINDING MACHINE.

Application filed January 25, 1924. Serial No. 688,592.

To all fr/0m t may concern:

Be it known that I, JAMES D. JOYCE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inWinding Machines, of which the following is a specification.

This invention relates ingeneral to winding machines, and moreparticularly to a winding machine having means for simultaneouslywinding a plurality of bobbins, each of which is separately andautomatically controlled.

It is an object of my invention to provide a novel and improved bunchbuilding means for winding machines of this type.

It is a further object of my invention to provide a novel and improvedcontrol mechanism for winding machines such that if the thread or yarnbeing wound breaks, the spindle of that bobbin will be automaticallythrown out of action. Means is also pro vided for automatically throwingthe spindle out of operation when the same is complete ly wound.

It is an object of my invention to provide a novel type'of brake means,automatically operating to stop the rotation of the spindle when thesameis thrown out of action.

It is a further object of my invention to provide a novel type oftravelling thread guide carrier, the follower of which can rotate in butone direction and thus provides against any back lash of the carrier.

Other objects and advantages of my invention will appear in theaccompanying specification and claims and will be disclosed in theaccompanying drawings in which- Figure 1 is a plan view of a portion ofmy device showing one of my opposed winding devices and a portion of mypower transmission system;

Figure 2 is a vertical section through the transmission housing;

Figure 17 is a view similar .to Figure 10 showing a modification of mydevice;

Figure 18 is a detail view of the arm acted on by the thread guide tolthrow out theclutch when the bobbin is full.

Referring with greater particularity to the drawings, and, for the firstportion of this specification, having reference especially to Figures1-13, inclusive, it will be seen that my device is comprised as follows:

My machine is adapted to drive a plurality of spindles arranged in twolongitudinally` extending banks or rows. Each spindle in each bank iseach mounted opposed to a spindle of the other bank so that thetwospindles are adapted to ybe operated by a. common operating means. Sincethe construction cf each of the spindle operating 1 means issubstantially identical, the description is limited largely to thedescription of but one of such means.

Referring lirst to Figures 1 and 2, it will be seen that the power forthe operation of my winding machine derived from any suitable source isapplied through a drive shaft 1. One end of the drive shaft 1 extendsinto a transmission housing l and has suitable bearings 1b. Mountedvonthe end of shaft 1 is a pinion gear 2, adapted to mesh with and drivealbevrel fgearf fsecured; to alg-stub shaft 4 mounted in suitablebearings in the housing. FiXedly secured to shaft 4 isa cam block 5having a cam track y5a in which-a pair of oppositely spaced rollers 6secured to rock arms 7 are adapted to travel. IThe rotation of shaft 4will thus result in the oscillation of the rock: arms 71and hence of therock shafts 8 on which the said arms are mounted. The rockingl ofshafts-8, asl-will be later described, provides forftheftraversingimoveinent' of thethread kguide and Vmany of the other of themoving parts ofmy device. ,l

Fixedlyf mounted on shaft 1 aiea'plurality of friction wheels 9, eachada-ptedat its periphery" to drive a pair of friction/disks 10, mountedfon shafts' 11 'to rotate therewith but' sldable` thereon,`r whichshafts carry the spindlesv on whichv the b'obbins 12 are tolbe wound.The thread y or yarn 13 passes through eitherl of two' thread-guides14aor 14h, the guide 14a being used whenthe thread is"y fedv from*belowv Ethey spindle and thefguide 14b being used when the threadisfed'from above. (See vFigures" 14 and 10). The thread then passesthrough the travelling thread guide 15 and'ov'erf a-bentf'p'in 16p o`nthe bunch building device'.

Reference being had especially'toFigures 1 and', it willbe seen that aclutch 17, which can be throwni'ntoor out of operation by a handle 18,is mounted on the shaft 8; This 'clutchis also capableof automaticcontrol, 4a'swill be disclosed'inthe following specification.

Mounted on^a`-collar a on'ishaftl Sris a substantially 'vertically`ertending rodv 20, y'to which there'is pivoted at 21 abat" 22, which baris; reciprocated longitudinally of.` the spindle by the oscillation ofJthe shaftxS. The bar 22-has 'secured thereto the bars 23 a1id'24` whichcarry one end of ythe rod 25, along which thel travelling .thread guidemoves,gandy the Shaper rod 26. The collar 2O*l is adaptedr tobeengagedby thel clutch n thfoghf alemana; or pin 1n'- aas-pred ythe frameof `the machine.

to bemo'ved into or outV of a slot 20h inthe col'lafr20a.y as vtheclutchism'oved longitudi- 7, 8"and` 10, it .will be seen that the'bent pinmounted on angai'nrBO, pivoted :at :31 toy a* member 32, which' in turnisv pivoticd to 'y he `end of the `arih' 30- lies against the under'face of' the few turns of thread which are manually wound on the bobbinas'fitI isplaced-in` position. VAs the spindle Vis put into operationthe thread'` is restrainedv from' the`-travers ing movement of the guide1-5 by the bent in 16'. `As'th'e bunch ,isbeing built, the end 34- ofthe arm 30 will be gradually push'edf'downwardly about the pivot ulltilthe inner end 35 of the arm 30 is in registration-'With a; slot 36,-inplate=567 secured to th'e 1fra'Inel The spring 38 w will then cause` thearm 3() to rotate about pivot 31,

`causing-.the bent end ofthe pin 16 to move out of engagement with thethread, and the ,wndinglproceeda the thread now being reciprocated alongthe bobbin by the guide 15.

"Thethreadfguidei14a is secured by means of a collar 40 to a rod 41. Onthe inner end of rod 41 there isffixedlyfmounteda curveda'rm 42;ca'rryingpins 243 between-which passes Qthe'farmi-44' which lcarriesthe thread guide* carrier 141". Iffthe thread guide 14a isb'eing usedandthe thread breaks,'the arm carrying 14l'will drop,` rotatingth'eshaft 41, arm 42, and byf'm'eans of'pins48 draws down on arm 44rotating thfe col1ar44f on the stud 45" to which collar arm 44E issecured. 'The collar 44a also carries a finger 46'w1hich rotates-*withinlf the threadiis carried by guide 145 thel z1n144 will fall whenthevthread breaks thus rotating the collar 44l andfinger 46.

Mounted on Irod 24 is a collar 47 (se'e Fig. 3") which reciprocatestherewith. A stub shaft 48 mountedin'the frameof the ma chine Carries afinger49 and a collar l50. Mounted onV the handle 18 is a'finger 51bearing against the periphery` of collar-50 and holding they clutch inei'igagem'ent against thet'ension of a spring 52, V'lfhefc'ol-4 lar' 47,atjthe end'of the outwardstroke of the ro`d'247 does not' quitereac'hthe linger 49.

Ifr the :thread: breaks, however, theythreads guides drop raisingy thefinger 46-intofthe path of the collar 47. Then,- as vthe rod 24 nearsthe outward en'd of its stroke, the collar v47 will strike theflinger 46whichinturn strikes thefinger49 movingthe shaft 48 longitudinally andmoving the collar 50 out ofcngager'nent with the finger 51.

The spring 52 will then .cause Vtheha'ndle 18th turn through apartialrevolution, and through the medium of the arm 55 and the pin 56, willthrow the clutch out of engagement, 'thevv pin ..56 .ridingin a-` groovein the clutch. y p

Pivoted on a pin 60, which is secured to the frame, is a lever 61, tothe outer endof which there is secured the spring' 52.l 'At the oppositeend of the lever 61i's a brake 62, so mounted that, when the spindlev isthrown out of action, the brake4 62 will strike the disk 10 pushing itaway from the drive wheel 9 and stopping the same.

'The lever 61 carries a' hooked finger 64 which isin engagement-withapin 65 on a cam member 66V rotatably mounted on shaft 11.' The cammember 66-is adaptedv to c'o`act with a cani 71 fixed on the shaft 11.When the clutch is thrown in,the lever 61 is raised by a pin 68 securedon an arm69 mounted onthe handle rod 18. This releasesthe pull on 65,and by means ofthe pull of a weight- 70, and the gradual pull of lightsprings 77 the cam member 66 will be rotated bringing the highestportion of its cam surface into engagement with the highest portion ofthe cam surface of the member 71, and thus moving the disk 10 intoengagement with the wheel 9 which drives the spindle, the clutch 66 anddisk 10 being secured together. It is to be noted that the clutch ismoved longitudinally of the shaft 8 in such a manner that, when theclutch is thrown out the pin 17a is withdrawn from its groove in thecollar 2Oa and the oscillatory motion of rod 20 is stopped.

l/Vhen the spindle is fully wound the arm of the thread guide carrierassembly will engage the nger 76 mounted on the shaft 41, thus partiallyrotating the shaft 41 and, through the medium of arms 42 and 44 willraise the 'finger 46 into the path of the collar 47 and throwing thespindle out of operation.

In Figure 16 I have shown a modification of my invention in which I havereplaced the cam, weight and spring clutch mechanism, 64, 65, 66, 70,77, by a compression spring 81 mounted on shaft 11 between the frame andthe disk 10. This spring is of less strength than the spring 52 so thatwhen handle 18 is rotated to throw the spindle out of action the spring52 acting on one endV of the lever 61 will force the brake 62 againstthe disk 10 and force the same, against the action of spring 81, out ofengagement with the wheel 9. Vhen the spindle is again to be placed inoperation the rotation of the handle 18 withdraws the brake from thedisk and the spring 81 forces the disk into engagement with the wheel.

In Figure 17 I have disclosed a modification of the mechanism shown indetail in Figure 11, especially parts 14h, 42, 43, 44, 45 and 46. Inthis showing I have done away with the curved arm 42, pins 43, and stud45 and have shown the finger 46 as twisted and secured directly to theshaft 41, to which the arm of carrier 14b is directly secured by meansof a suitable collar.

Referring now especially to Figure 6 it will be seen that the rods 23and 24 are secured to each other by plate 28, the arm 23 being extendedat 27 to form a support for the Shaper 26 xedly secured thereto.

The plate 28 has a longitudinally extending slot 28 in which a pinsupporting one end of the rod 25 is adapted to travel. The other end o-frod 25 is pivoted at 82 to a plate 83.

By reference to Figure 9 it will be seen that I have provided a spring84 one end of which is attached to a finger extending from the rod 23and the other of which is secured to a finger extending from the rod 25.This spring tends to bring rod 25 into alignment with the rod 24. Asuitable friction collar is provided with spring 86 abutting a collar86a and is adapted to bear against the edge of plate 28.

A linger 87 has an undercut portion 88 adapted to bear on the edge ofthe shaper,

the finger being mounted on a portion of bers are secured to collars 91and 92 which are mounted on a sleeve 93 on rod 25. The sleeve 93 hassecured thereto, by means of a collar 94, a follower wheel 95 theperiphery of which is adapted to touch the yarn on the bobbin as it iswound and thus rotate the wheel. Pivoted to the wheel 95 at 96 is a bentarm or yoke 97 which is shaped as shown in Figure 11 to provide ahousing for a worm gear 98 and bearings for the shaft 99 on which thesaid worm is mounted. The gear 98 extends through a recess 98 in thesleeve 93 and engages the threaded rod 25 with which it is, held inengagement by a spring 100. The rotation of the wheel thus results inthe whole thread guide assembly' being moved along the rod 24.

A spiral spring 102 is wrapped tightly around the extended arm of theshaft 99 in the manner shown in Figure 11. The inner end of the springis held in position by yoke 97. While the worm 98 can be rotated in acounterclockwise rotation as viewed in Figure 12) it will be seen thatany attempt to rotate the Worm in the opposite direction would cause thespring 102 to bind the shaft 98 and prevent rotation. To move the threadguide backwards then, it is necessary to raise the yoke 98 about itspivots against the actionfof spring 100. The carrier can thenbe movedYback to any desired position, the sleeve 93 now sliding freely on therod 24.

In the device shown in Figure 14 I have dispensed with the double rod23, 24, 25, 27 and' have substituted a single rod 25. The shaper isnaturally dispensed with and the bobbin wound is, when completed, asshown iu Figure 15.

The operation of my device having been fully disclosed, it will be seenthat I have provided a winding machine for simultaneaously winding aplurality of bobbins, each bobbin being independently and automaticallycontrolled in its winding, having novel means fo-r automaticallythrowing a bobbin into or out of operation when the thread feeding itbreaks or when the bobbin is fully wound; which has a novel and improvedtype of bunch builder; and which is simple in construction andoperation.
